i am having some quite serious bugs with jit.qt.grab, most of the time resulting in max to quit instantly without any error messages. this patch used to work fine like two months ago...
the patch captures an incoming 1080psf25 video signal via "jit.qt.grab 1280 720 @unique 1 @interp 1 @colormode uyvy". this used to work fine a while ago, however now this results in an instant max shut down. it becomes slightly more stable if i do all these commands one after another (like first capture 1920x1080, then rescale with interpolation in a separate matrix, then convert to uyvy via jit.argb2uyvy) but this uses up too much performance and does also quit randomly from time to time.
i'm running max 6.1.7 (in 32 bit mode) on macos 10.9.2 with a video signal coming in over a blackmagic express card (driver version 10.1).
any help is appreciated a lot!
